Building the Electronic Learning Materials to Support Teaching Topics "Materials" and "Energy" in Science 4 According to the 2018 General Education Curriculum

The research paper focuses on the design of construction processes and the use of e-learning materials to support teaching and learning topics “Materials” and "Energy" in Science 4. Once we have built and uploaded online lectures to the Internet, teachers and students can utilize them in a flexible manner for classroom instruction or self-learning. In this article, we used the document research method to build a set of electronic learning materials on the topics “Materials” and "Energy" in Science 4. Additionally, it used expert methods to collect feedback from six lecturers at the Thai Nguyen University of Education and 32 primary school teachers. We experimented with a group of 30 students in the 4th grade, and the results showed that the e-learning material that we built helps students improve their autonomy and self-study, encouraging them to learn their prior knowledge at home by studying online lectures on the YouTube channel and questionnaires on the Azota app. Early research results showed that this electronic learning material has helped teachers and students teach and learn Science 4.
